SPINDLE FOR SPINNING, TWISTING, AND LIKE MAGI IINES.

Specification of Letters Patent.

Patented Feb. 18,1913.

Application filed May 31, 1912. Serial No. 700,716.

To all whom it may concern:

Be it known that I, ALBERT H. MORTON, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented cert-ain new and useful Improvements in Spindles for Spinning, Twisting, ,and the Like Machines; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to spindles for spinning, twistingand the like machines, and more particularly to the bobbin clutching means which are employed in connection with such spindles.

The object of the present invention is to reorganize and improve the bobbin clutch ing means used for clutching bobbins in driving engagement with the spindles of spinning, twisting and the like machines.

To this end, the present invention consists in the improvement in bobbin and spindle connecting means hereinafter described and particularly defined by the claim.

In the accompanying drawings illustrating the preferred form of the invention Figure 1 is an elevation of a spindle embodying the invention in its preferred form and showing in section a bobbin applied thereto; Fig. 2 is a detail illustrating a sectional elevation of a portion of the spindle; and Fig. 3 is a section taken upon the line 38 of Fig. 2, looking in the direction of the arrows.

In the illustrated embodiment of the invention, the spindle blade 1, its whirl 2 and the whirl base 3 are, except as hereinafter pointed out, of any usual or preferred con struction. The collar or blade gripping portion 4 of the whirl base 3 embraces the spindle blade with a driving tit and rigidly secures the whirl to the blade. The upper face of the whirl base constitutes a bobbin rest for supporting and vertically positioning the bobbin on the spindle. The blade gripping portion 4 of the whirl base is extended above the bobbin rest and is adapted to be received in the opening in the lower end of the bobbin.

In accordance with the present invention, the bobbin is tightly clutched to the 'spindle by a clutch member 7, which consists of a collar 8 loosely embracing the spindle blade 1 and having a plurality of depending arms 9 formed integral therewith. The arms 9 are bowed outwardly adjacent the collar and then project lengthwise of the spindle to present a substantially cylindrical surface to the interior of the bobbin. The free ends of the arms 9 are loosely supported in an annular clutchmember-receiving recess formed in the bobbin rest, and a vertical pin 10 secured in the bobbin rest and projecting into the re; cess between two adjacent arms serves to lock the clutch member to the spindle. The lower ends of the arms 9 are provided with out-turned feet 12 which are received in the annular recess beneath an inturned'flange 13. The clutch member is formed of a resilient material and is applied to the spindle by contracting the arms and allowing them to drop into the recess, the resiliency of the arms then causing them to expand, positioning the feet 12 beneath the flange 13 and preventing the removal or displacement of the clutch member when the spindle is empty. With this construction, the clutch member has provision for some vertical and lateral movement relative to the spindle. The bobbin 15 is of the usual form having an enlarged bore at its lower end provided with a bushing 16. The diameter of the bore is slightly less than the diameter of the surface formed by the clutch members, thus causing the arms to be contracted when the bobbin is applied to the spindle, clutching the bobbin firmly to the spindle.

The present invention is not limited to the illustrated embodiment thereof, as it may be embodied in other forms within the scope of the following claim:

A spindle for spinning and the like machines, having, in combination, a spindle blade, a collar having an annular recess and an inturned flange, a bobbin clutching member consisting of a plurality of resilient lneans arranged to lock the clutch member arms extending lengthwise of the spindle against rotation, relative to the spindle, and integrally connected at their upper ends substantially as described.

to a collar loosely embracing the spindle ALBERT H. MORTON.

5 blade and provided at their lower ends with Vl itnesses:

out-turned feet normally positioned beneath. HORACE VAN EVEREN, the flange upon the recessed collar, and ALICE AcKRoYD.
